Abstract:

Vibration is an oscillation wherein the quantity is a parameter that defines the motion of a mechanical system. The main causes of vibration are unbalanced forces in the machine, dry friction between the mating surfaces, external excitation, earthquakes, wind self-excited vibrations, misalignment of rotating shaft, looseness in rotating machinery, loose foundations and excessive bearing clearances, oil whirl in bearing. The harmful effects of vibrations are excessive stresses in machine parts and undesirable noise. Also due to high vibration there are looseness of parts and partial or complete failure of parts. This vibration phenomenon is used in some musical instruments, vibrating conveyors, shakers, vibrating screens, stress relieving. This vibration can be reduced by removing the causes of vibration, by vibration isolation. Also vibration can be controlled by using shock absorbers and by installing dynamic vibration absorbers. Using composite material also vibration reduce. Automobile suspension Leaf spring consist high vibration during motion. By binding the composite material to steel spring the vibration can be reduced. ANSYS software used for Finite Element Analysis for vibration analysis.
